Answer 1

Common Foods That Are Harmful Or Even Fatal to Dogs


Avocados (fruit, pit, and plant)
They can cause difficulty breathing; fluid accumulation in the chest, abdomen and heart; or pancreatitis.

Onions
Onions destroy red blood cells and can cause anemia, weakness, and breathing difficulty. Even small amounts can cause cumulative damage over time. This includes onions or chives - raw, powdered, dehydrated, or cooked.

Garlic
Large amounts of garlic cause the same problems as onions.

Grapes and Raisins
Can cause kidney failure in dogs. As little as a single serving of raisins can kill him. If the dog doesn't eat enough at one time to be fatal, he can be severely damaged by eating just a few grapes or raisins regularly.

Tomatoes
Can cause tremors and heart arrhythmias. Tomato plants and the most toxic, but tomatoes themselves are also unsafe.

Nutmeg
Can cause tremors, seizures and death.

Caffeine (from coffee, coffee grounds, tea, or tea bags)
Stimulates the central nervous and cardiac systems, and can cause vomiting, restlessness, heart palpitations, and even death within hours.

Diet products containing the sweetener Xylitol
Can cause a sudden drop in blood sugar, resulting in depression, loss of coordination and seizures. Unless treatment is given quickly, the dog could die.

Macadamia nuts
Can cause weakness, muscle tremor and paralysis. These symptoms are usually temporary.

Walnuts
Walnuts are poisonous to dogs.

Chocolate
Can cause seizures, coma and death. Baker’s chocolate is the most dangerous. The darker the chocolate, the more dangerous it is. But any chocolate, in large enough amounts, can kill a dog. An ounce of chocolate can poison a 30-pound dog, and many dogs will happily consume more than this. The symptoms may not show up for several hours (and so might make you think all is well), with death following within twenty-four hours. A dog can consume milk chocolate and appear to be fine because it is not as concentrated, but it is still dangerous.

Apple seeds, cherry, peach, plum, apricot pits, and pear pips
Contain cyanide, which is poisonous.


Too much salt
Can cause kidney problems. Also, large breeds of dogs that eat salty food may then drink too much water and develop bloat, which is fatal unless emergency treatment is given very quickly.

Too much fat or fried foods
Can cause pancreatitis.

Ham and bacon
Contain too much fat and too much salt, and can cause pancreatitis. Also, large breeds of dogs that eat salty food may drink too much water and develop a life-threatening condition called bloat. This is where the stomach fills up with gas and within several hours may twist, causing death.

Raw liver or too much cooked liver (three servings a week)
Can lead to vitamin A toxicity. This can cause deformed bones, excessive bone growth on the elbows and spine, weight loss, and anorexia. Check the label of your canned dog food to be sure that it does not contain liver if you are giving your dog liver also.

Wild mushrooms
Can cause abdominal pain, drooling, liver damage, kidney damage, vomiting, diarrhea, convulsions, coma, or death.

Raw egg whites
Contain a protein called avidin, which can deplete your dog of biotin, one of the B vitamins. Biotin is essential to your dog’s growth and coat health. The lack of it can cause hair loss, weakness, growth retardation, or skeleton deformity.

Grains
Should not be given in large amounts or make up a large part of a dog’s diet, but rice is generally safe in small amounts.

Cooked bones
Can splinter and tear a dog’s internal organs.

Most Vegetables whole or in large pieces.
Dogs can't digest most vegetables (carrots, green beans, lettuce, potatoes or yams) whole or in large pieces.

Potato peels and green potatoes
Are dangerous, dogs can't digest.

Dairy products
Are high in fat, which can cause pancreatitis, gas and diarrhea. A small amount of non-fat, plain yogurt is usually safe.

Answer 2

The toxicity from grapes and raisins are still not understood. Toxicity has been reported from as little as a single serving of raisins however. Onions and garlic can cause anemia but it takes quite a while for this to have an effect.

Answer 3

The comment about chocolate being more poisonous to pure bred dogs than mongrels is rubbish. I have heard that some gundogs are actually given a Mars bar to keep their energy up whilst on a shoot.
I am not aware of any human foods that are "instantly poisonous" to dogs. One ounce of dark chocolate is sufficient to kill a labrador. Some people give their dogs garlic to prevent worms. My dogs have the odd square of milk chocolate, the odd grape, (if there is any) curry remains (containing onion & garlic).
As with most things it is a case of don't panic - use common sense. We seem to have lost the ability to use common sense whilst hanging on every word of "experts".

Answer 4

I heard another question saying the same thing about grapes but dont know if its true. I know chocolate isnt good for dogs unless they are the ones made for dogs. Someone said avocadoes were bad for dogs but one of my dogs eats them and really likes them when they fall off the trees in the garden. Dont know of anything else though.

Answer 5

Chocolat is poison to a dog, 6 oz of bakers chocolat will kill a 60 pound dog. Some dogs have a hard time with apple seeds (arsenic). Unless your friends are professional dog breeders I would differ to the pros. Do a yahoo search for foods harmful to dogs. But stay away from rumors of food harmful to dogs.

Answer 6

Yes grapes and onions and raisins are bad for dogs.

So are chocolate and milk.

Answer 7

they are pulling your leg babe. A dog will tolerate anything in moderation. The worst thing for your dog is chocolate but small bits will not harm them. Dogs arent stupid and will not eat what is going to kill them. By the way unlike someone said above onions are good for your dog, it keeps them free of worms. and not toxic at all. Ex breeder. And again we use boiled potatoe skins with our dogs food and they love raw ones, never been sick yet.

Answer 8

My poodle ate grapes, onions, and raisins (actually he would eat anything) and they never seem to bother him. He did die last month but he was >14 years old so go figure.

Answer 9

well my dogs have a 'little bit of everything' from the 'foods dangerous to dogs' list! the only thing that i will not give them in large amounts is chocolate-it does contain theobromine which is poisonous to dogs, although they do have the odd bit of mars bar on the odd occasion! but try to tell my 13 yr old dog that she cant have the remains of last nights chinese, complete with onion and fried rice! i think she would eat me! they also eat baked tatie skins, bananas, apple cores, orange segments, lemons-the older one loves lemons! they drink cups of tea, eat spilled rabbit mix, basically they eat ANYTHING they can get their paws on! and they have eaten this way right from being young dogs, but i think its like anything else-use your common sense-give them 'bad' foods in moderation and if you find that your dog reacts in a bad way-dont feed that particular food again.

by the way i forgot to mention that they love cherry toms, raw eggs, button mushrooms, carrots, cabbage and sweetcorn, milk, yoghurt and best of all they love to gnaw on whole lamb ribcages! good excercise for their jaws, keeps their teeth clean and lets them regress back to the 'wild' for a couple of hours!

Answer 10

I only know about chocolate being poisonous for dogs.

Try that link. I've heard the same thing. I think it's more of a danger if you've got a pure bred. My friend has a 13 year old dog that is crossed lab/german shep. and she feeds that dog everything. I mean everything. Even chocolate. I don't feed my dog everything but I have 3 kids. She has had a taste of it all and she's ok. Now don't go feeding your dog everything now though!!
